ERASER rATTACHMENT FOB PENCILS.

To all ici/wm t may concern.'

Be it known that I, WADE W. `lVIooRn, a citizen of the United States, residing in the city of Pittsburg, in` the county of Contra Costa and State of Caliliornia, have invented a certain new and useful lmprovementin Eraser Attachments for Pencils, of which the following is a specification.

My invention relates to improvements in eraser attachments for pencils of the type having a` permanent body portion and a magazine therein, for extraleads and com- `prises means i'or securing an eraser to the end said pencil. y

A further object of the invention is to provide a new and novel means for securing an eraser cup and retaining means to the end of a lead magazine.

A. still further object of the present invention is to, provide a newy and novelmethod for detachably connecting anr eraser inclosing means within the magazine operating knob.

Other objects willhereinafter be more` fully disclosed. .f Y

This invention has forits primary object a new, improved and simple `means .for attaching an eraser to the type of pencil dis-r closed in my copending a plication, filed December 1st, 1919, Serial o. 342,022, rei'- erence to which specification is hereby made for a full comprehension oi said pencil.

I accomplish these several objects by means oi' the improved device disclosed in the drawings forming a part of the present specification wherein like characters of reference are used to designate similar parts throughout the said specification and drawings, andv in which:

Figure l is a broken elevation of a pencil disclosing the inclosing knob removed and in vertical section;

Fig. 2 is an enlarged broken detailed view, partly in vertical section, disclosing-more fully the details of construction;

Referring to the drawings the numeral 1 is used to designate a shell or body withinr which is rotatably mounted a threadedv Specication of Letters Patenti. Patented Sept, 14, 1920 Application flied December 1, 191e.r serial No. 342,021.

`ninternally and externally threaded cupk .and held therein bythe detachable engagement of a screw 7 arranged axially within the cup 3. A 'solder filling S is provided to rigidly and permanently retain the cup 3 to the end of the magazine 2 andalso to retain the screw 7 permanently within said cup 3. The eraser 6 is further retained within the cup 3 by engagement with the internal threads'of said cup 3. Y

An ornamental knob 9 is provided with an internally threaded annular flange ll adapted to engage the external threads of the cup 3 and to inclo'se saidy cup 3 therein. f

In ordinary use the knob 9 is mounted, by means of the threaded lange y1l upon the cup 3 and magazine 2. When the eraser G isrejquired ytheoperator grasps the depending flange lofthe cup 3 and the knob 9 and unscrews said knob from said'cup when the eraser will then be exposed for use. i f f After using said eraser 6 the knob 9 is again screwed, by means of the internally threaded ilange 11, upon the cup 3 thereby providing an ornamental inclosure for the eraser 6.

The novel construction consists in the solder illing 8 which simultaneously secures the cup 3 to the vmagazine 2 and the screw 7 within the cup 3. v

By means oi" this simple and novel arrangement the parts are permanently secured together and simple means are thus provided for detachably and eil'ectively retaining an eraserv on the end of the pencil.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The combination with a pencil, comprising a magazine and a shell surrounding the magazine, of a cup mounted upon the end of the magazine and provided with an anand eraser 6 f nular `flange tofsurround the shell of said pencil; an eraser mounted within the cup; means for retaining said eraser within said cup; and an ornamental knob adapt-ed for engagement with the cup to inclose said cup and eraser therein.

2. The combination with a pencil, comprising a magazine and a shell surrounding the magazine, of an internally threaded cup mounted upon the end of the magazine and provided with an annular flange surrounding the adjacent end of the shell; an eraser mounted within the cup; means for retaining the eraser within theV cup; and an ornamental knob arranged to surround said cup and having an internal flange adapted for detachable engagement with the cup.

3. The combination with a Jencil comprising a magazine and a shell surrounding the magazine, of an internally threaded'cup mounted upon the end of the magazine; an eraser within the cup; a screw mounted within the cup and arranged to engage and retain said eraser within said cup; and an ornamental knob surrounding the cup and eraser therein and arranged for detachable engagement with said cup.
